            <h2 id="功能介绍">功能介绍</h2>
<p>在使用用户名和密码登录功能时，需要填写验证码，验证码是以图形化的方式进行获取和展示的。</p>
<h2 id="验证码使用原理">验证码使用原理</h2>
<p>验证码的使用流程和原理为：在服务器端负责生成图形化验证码，并以数据流的形式供前端访问获取，同时将生成的验证码存储到全局的缓存中，在本案例中，我们使用redis作为全局缓存，并设置缓存失效时间。当用户使用用户名和密码进行登录时，进行验证码验证。验证通过即可继续进行登录。</p>
<h2 id="验证码库安装">验证码库安装</h2>
<p>借助开源的验证码工具库可以生成验证码。
首先，安装开源的验证码生成库：</p>
<div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-go" data-lang="go"><span style="color:#66d9ef">go</span> <span style="color:#a6e22e">get</span> <span style="color:#f92672">-</span><span style="color:#a6e22e">u</span> <span style="color:#a6e22e">github</span>.<span style="color:#a6e22e">com</span><span style="color:#f92672">/</span><span style="color:#a6e22e">mojocn</span><span style="color:#f92672">/</span><span style="color:#a6e22e">base64Captcha</span>
</code></pre></div><h2 id="验证码代码示例">验证码代码示例</h2>
<p>在下载后的base64Captcha库的目录中，可以看到有_example和_example_redis两个目录。第一个example是用于演示生成验证码和验证码的示例代码。</p>
<p>按照示例代码的说明，运行程序并在浏览器进行端口访问：</p>
<div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-go" data-lang="go"><span style="color:#66d9ef">go</span> <span style="color:#a6e22e">run</span> <span style="color:#a6e22e">main</span>.<span style="color:#66d9ef">go</span>
<span style="color:#75715e">//浏览器中访问：http://localhost:8777
</span></code></pre></div><p>如下图所示：</p>
<p>
        <a data-fancybox="gallery" href="https://www.qfgolang.com/wp-content/uploads/2019/11/WX20191108-183533@2x.png">
            <img class="mx-auto" alt="img" src="https://www.qfgolang.com/wp-content/uploads/2019/11/WX20191108-183533@2x.png" />
        </a>
    </p>
<p>通过自定义配置，可以选择不同的生成验证码的参数，并刷新验证码，同时还可以对验证码进行验证。</p>
<p>通过exmaple目录下的main.go程序可以看到生成验证码和验证验证码的逻辑，此处不再赘述。</p>
<h2 id="项目集成验证码生成和redis缓存">项目集成验证码生成和Redis缓存</h2>
<p>通常来说，验证码都是有一定的实效性的，过期验证码也就无效了。</p>
<p>因此，我们考虑在项目中引入Redis作为数据缓存。当验证码生成后，将验证码存放在Redis中，并根据配置文件对Redis进行设置。</p>
<h3 id="安装go-redis库">安装go-redis库</h3>
<p>在项目中使用redis,需要安装go-redis库，可以在https://github.com/go-redis/redis中查看如何下载go-redis和配置。</p>
<h3 id="增加redis配置">增加Redis配置</h3>
<p>在配置文件app.json中新增redis配置：</p>
<div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-go" data-lang="go"><span style="color:#f92672">...</span>

    <span style="color:#e6db74">&#34;db&#34;</span>: <span style="color:#ae81ff">0</span>
}
<span style="color:#f92672">...</span>
</code></pre></div><p>同时，新增RedisConfig结构体定义，如下所示：</p>
<div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-go" data-lang="go"><span style="color:#66d9ef">type</span> <span style="color:#a6e22e">RedisConfig</span> <span style="color:#66d9ef">struct</span> {

}<span style="color:#a6e22e">Copy</span>
</code></pre></div><h3 id="redis初始化操作">Redis初始化操作</h3>
<p>进行了redis配置以后，需要对redis进行初始化。可以封装redis初始化操作函数如下所示：</p>
